Warning!
Moisture which gets on the brakes during a
car wash can reduce braking efficiency or
make the brake pull unevenly which could
increase the danger of an accident, causing
serious personal injuries or death.
f After washing the vehicle, test the brakes and
steering and briefly brake the discs dry.
When doing so, make sure that vehicles travel-
ling behind you are not affected.
Automatic car washes
f Please see the chapter "WIPER BLADES" on
Page 261.
Optional add-on parts or parts which project be-
yond the contours of the vehicle may be damaged
by design features (e.g. brushes) of automatic car
washes.

Maintenance and Car Care
The following parts are particularly
susceptible to damage:
– Windshield wipers and rear wiper (always
switch them off – wiper stalk in position 0 – to
prevent them wiping unintentionally in intermit-
tent or sensor operation).
– Door mirrors (always fold in).
– External antennas (always unscrew).
– Roof Transport System (always remove com-
pletely).
– Off-road roof-mounted headlights (always
remove completely).
– Spoiler.
– Wheels (the wider the rim and the lower the tire
height, the greater the risk of damage).
f Please consult the operator before using
automatic car washes.
f Wash and dry by hand all points not reached by
a car wash, such as door and lid seams or
door sills.
Note
Automatic car washes spray water at odd angles
and high pressures, which are not seen in normal
driving. Therefore, water can sometimes find its
way into the passengers compartment during or
shortly after the car wash.
